Presidents Day: Presidential birthdays equal a hotel discount

The Renaissance Blackstone Chicago Hotel is a landmark hotel that opened… (Renaissance Blackstone…)

Teddy Roosevelt slept here, and so did Jimmy Carter. It's the landmark Renaissance Blackstone Hotel Chicago, which honors U.S. presidents and President's Day with a quirky room discount: If you share your birthday with a president, any president, pay your age for a night's stay -- whether you're 35 or 105.

The deal: I found a list of birthdays for the 44 men who have served as president. (I share a birthday with Harry Truman.) You have to stay the night of your birthday to take advantage of the deal.

When: The offer is good through Feb. 16, 2014, based on availability.

Details: You won't see the discount on this deal until you present a valid ID showing your birth date when you check out.

No rooms were available on May 8, the birthday I share with Truman, when I checked availability online. I checked again for anyone who has an Aug. 4 birthday in common with President Obama and found a room with a king-sized bed, for $509 a night plus tax. Depending on your age, you save at least $410 for the night.
